Ok after flashing my BIOS back to F5 version, btw really worry about it because maybe it could break my BIOS, now except for the USB issue everything is working properly, no more bsod or instabilities, but not USB 3.1 either.
Now after flashing my BIOS back I lost my Mac address in the BIOS(out off topic if anyone knows how to fix this)
Gigabyte state I need BIOS version F21 to be able to install USB 3.1 drivers, but I can't use this one because It gives me issues to boot into window
Do you think flashing the BIOS up and back can be safe?
I tried all the solutions provided here, none of them have worked. Thanks very much for all your help anyway.
By the way between those BIOS flashing I was able to install thunderbolt but when I started the computer say I need an update and open a web site to download it but my motherboad is not listed there.
Identify your product, then click on the link below to go to the product page. Click on “Support and Downloads”. Choose “Utility” under Download Type and follow all directions. Remember to install the Thunderbolt driver before installing the Thunderbolt FW Update Tool.

See the next 3 posts starting here. Download the files then go here. Haven't actually done this myself, so If you do, let us know how it went. BTW it was stated that downgrading your BIOS using the ftp DOS method (which I assume you used) would overwrite the MAC address, which is why I'm hesitant to use it. .

Not sure where you see you need the F21 BIOS to "install USB 3.1 drivers" but that's false. If that were the case, you wouldn't have been able to use the feature when the boards first came out.

As for Secure Boot - Were you using Secure Boot before the BIOS update? Did you remember to reset you the BIOS for it. See my post here on properly setting up Secure Boot.

Knowing what I know now, unless you plan on running a Kaby Lake Processor, I'd stay away from these updates. Too many weird issues happening. And I'm one to NEVER say don't update a BIOS.

Definitely!!!

I've modded my own high-end desktops with these win-raid drivers and they work better than the stock MS drivers supplied by default.
HTH,

How? Performance numbers to back that up?

Anyway the issue is not the 3.1 drivers, but the flaky Gigabyte F21 BIOS update hosing stuff. It has noting to do with 3.1 drivers. And I know the OP mentioned he couldn't install the 3.1 driver until the update, but that's highly questionable stated in my reply to that statement.

And yes, I run a Z170 gigabyte board supporting USB 3.1. And though I don't have any 3.1 devices, the port did work as advertised with both USB 2 and 3 devices... before the F21 BIOS was even a thought.

After flashing my BIOS again today to version F21 and even trying their more recent beta F21c I have to go back to version F5, I was able to install properly the thunderbolt driver and the USB 3.1 update tool, even if everything ran ok it didn't work, I turned off the computer for more than one hour (they suggest 30 sec) unplugged. I even remove the battery. When I got back into window now I had 2 unspecified devices to safety remove. Important to mention that Everytime I log into window a window showed up telling me that thuntherbolt need an update with a link to gigabyte website, the same place I downloaded the same driver, crazy.
I ended turning off Thunderbolt in the BIOS and the 3.1 in device manager, now I have a motherboard that supposed to support USB 3.1 but seems not.
I give up, the computer is running ok despite the USB issue, I learned the lesson with gigabyte and I hope soon be able to upgrade to an Asus and i7 7700k.
Btw I was able to modify my Mac address with guide provided here, just read carefully because you can use that guide to upgrade your nic firmware but you don't need to touch that just the hex editor and the Intel tool, it worked like a charm.

The correct behaviour of windows update over a metered connection is to offer the choice to download, or wait until on a non-metered connection.
